Splenic metastasis of lung cancer

Splenic metastasis from a lung cancer is infrequently noted, however, the p attern of the metastasis has not been studied, thus we conducted a retrospe ctive study. Twelve of the consecutive 997 patients with lung cancer., who were admitted to our division, developed splenic metastasis. The pattern of splenic metastasis involved solitary nodule in 7 patients (58.3%); multipl e nodules in 4, and microscopic metastasis in 1. All of the 12 patients had other abdominal organ metastasis. Splenic mass accompanying metastasis to other abdominal organs in a patient with a known lung cancer should be rega rded as a metastasis.
